TO ALL WHOM IT MAY OONCERN Be it known that I, THOMAS PLACE, of Alfred Centre, in the county pf Allegany, and State of New `York, have invented a new and improved Machine for Boring and Tenoning; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in thc art to make and use the same, reference being had to the accompanying drawings, forming part ol" this speciieation, in Which- Figure 1 is a vertical longitudinal section, taken in the line a; x, lig.

Figure 2 is a top view of my improved boring and tenoning machine.

Figure 3 is a detached View of a part of the machine for holding` fello'es to be bored.

Figure 4 is a top View of the same.

Similar letters of reference indicate like parts.

The objcctof this invention is' to provide a labor-saving machine for the useof whcelwrights, by which, with the ordinary tools of the shop, the tenons may be cut ou spokes, and the holes bored in felloes, with dis. patch und accuracy, so that they will fit exactly, and may be 'put together to form a perfect Wheel. I

i .A is-an ordinary rectangular bench frame, having at the right-hand end a high standard, B, on the front side of which is fastened a cast-iron frame, C, for supporting` a bit-stock, to be used for boring and tenoningv The plate a is bolted to the standard D in front; it is slotted and grooved to serve as a guide to the block 5, which holds the front end of the bit-stock c, and is moved up and down for adjustment by means of the screw d, as shown in iig. 1. By means of a set-screw, e, the bloelr I) is held irmly at any height on the'plate a, when adjusted to suit the work in hand. The head of the bit-stock eis held in a block, fixed on a short standard, w, set in grooves on the outer end of the frame C. The standard "w moves to adjust the blocks b, Z7 to suit. bit stocks ofvdiierent sizes, and the set-screivg holds it in place. The head end of the bit-stock is fitted into the block t', and the front end has lead or other soft metal run in around it, to form a bearing in the block vIn the block'b a slot is provided on one side, for the play of thebit-catch or spring. A sliding carriage, D, isV fitted in the bed of the frame A, which carriage'is moved back and forth by a treadle, L, that is connected byA an elboiv-lever, 7c, with an adjustable rack, z', fastened to the carriage D. On the rear end of the carriage D is placed a round block, m, made movable, of-dilferent sizes, to t in and hold the hubs of Wheels, which are set upon it to have the spokes eut to length with tenons,las shown in figs. 1, 2. The movement of the carriage is regulated by an adjusting stop-bar, n, which is fixed to suit the length of the spokes by a set-screw, o, and stops against the standard B when the tenon is cut the right length.`

For cutting the tenons on the spokes a proper tool or hollow auger is put in the bit-stoek c, and theA opera- .tion is performed very quickly and accurately, after adjusting;` the parts and placing the hub, with the spokes in it, asvbefore described, by placingz,r one foot on the treadle it, to draw the spoke to the Work, and with the right hand'turning-the bit-stock till the stop-bar n arrests the movement of the sliding carriage D. Thus all the spokes on a Wheel have their tenons eut exactly the same length, and the wheel they form will beper'eetlv round and true.

For boring felices, or any other article' to which it' may be applied, a movable or detached bed or platform, E, is tted upon the sliding 'carriage D, to move with it, as shown in figs. 3, d. On the platform E is fastened a screw-clamp, s, so formed as to hold a felloe firmly when it is to be bored, by moving up to an auger placed in the bit-stock c, in the same manner as for-cutting tenons. Holes are thus bored to a gauge in felloes YWiththe same accuracy that the tenons are cut on spokes, so that they will lit each other exactly, and make a perfect Wheel when. put. together. This work is done on the machine, therefore, much better than by hand inthe ordinary Way. I

Having thus described my invention, I claim as new, and desire to secure by Letters Pateit-f The sliding carriage D, having adjustable rack z', adjustable stop n, and elbow-lever t, and operated by the treadle h, and operating substantially as described for the purposeispecied.
